JBJ power compacts- is this the right lights?

Txcowboy22 · #1 12/14/2007, 03:03 PM

I am just wondering why the corals that I buy from my lfs are much more colorful there then when I get home? they seem to keep their color for a week or 2 then they fade. BUT the colors are great when just my atintic light is on. My white light is brands new and the atintic is a little bit older about 6 months. I have a 46 bowfront with 2 96 watt pc, any ideas??????????????

what corals are you buying? what lights do they have at the petstore? and most importantly how the quality of your water(parameters)?

The store has them under pc, I am buying polyps and mushrooms mainly. I know if I go with 2 blue lights the color is much much better. I have had this tank for a little over a year. nothing has died in 6 months, I couldn't tell you my exact water readings b/c I am at work. but the salinity is around 24 and everything else should be around nitrite 0, amonia 0, nitrate 0 or so

24 for salinity is low, it should be around 32. That might be causing stress on the corals. Whats is you PO4 level?

32???? WHAT!

Unless you are talking about specific gravity at 1.024, then that would be ok
